PROBLEM TO BE SOLVED: To provide a method for manufacturing a sheet with a fine uneven shape which can facilitate releasing from a mold by a 2P molding process using a roll-like mold. SOLUTION: The method for manufacturing the sheet with the fine uneven shape comprises a process of coating the surface of the roll-like mold with a fine uneven shape which is a reverse shape to a specified pattern with the first ionization radiation-curable resin, a process of coating a photo-permeable resin base material with the second ionization radiation-curable resin, a process of pressing the photo-permeable resin base material on the roll-like mold to laminate the first and second curable resins, a process of curing the ionization radiation-curable resin made by laminating the first and second curable resins by irradiation with an ionization radiation to transfer the fine uneven shape, and a process of releasing the photo-permeable resin base material integrated with a reaction cured product of the ionization radiation-curable resin made by laminating the first and second curable resins from the roll-like mold. The above described processes are characterized by that the reaction cured product of the first ionization radiation-curable resin has a higher releasability than that of the reaction cured product of the second ionization radiation-curable resin.
